| Main Objective: As good responsiveness to corticosteroids is a hallmark of asthma (1), this response is likely able to discriminate between asthmatic children and non-asthmatic subjects. So far, response to inhaled corticosteroids has not been used as a predictor of asthma in studies, although several international guidelines advocate a trial treatment with inhaled corticosteroids for a likely diagnosis of asthma in young children. This study can test whether such guideline advises hold in clinical practice. ;Secondary Objective: ;Primary end point(s): Effects of medication on: - Nitric oxide (NO) in exhaled breath - Breathogram of volatile substances in expired air - Exhaled breath condensate - Lungfunction measurements of airway resistance - Respiratory symptoms and quality of life | — |
